How did I miss this episode?  Who knew that Optimus Prime took time out of his busy schedule to appear on the David Letterman show?  Here's the Top Ten Things That Sound Cool When Spoken By A Giant Robot.  Nice catch by Collider.

Nice. this is terrific, "It was so hot in Central park today, i saw a Squrriell rubbing sunblock on his nuts"

That was funny. Optimus Prime was always my favorite Transformer since I started likeing Transformers.
Optimus Prime your the man........I mean you are the robot.

Eh it was alright. Very good for Dave though. lol I did Love #1.

thanks for posting this G-Man....I had heard they were doing this but forgot about it yesterday

Number six was hilarious!

number 1 was very funny

Omg, that voice.....
sooo attractive ^^

solid. gold.

Number ten with the Jergens lotion was definitely my favorite

This made me smile :D

I chuckled.

I think my favourite one was the Sex and The City line. That sounded hilarious coming from Optimus.

hilarious

"Omg, that voice.....sooo attractive ^^"

Pure awesomeness!

That was pretty funny. There are lots of things I'd like to hear spoken by Optimus Prime.

That last one was great. I also love the Facebook one.

That was great. Sounds like Peter Cullen had a lot of fun there.

Peter Cullen is the man!!!

I found #2, the one about the rabbi to be kind of odd. Because one time I was on the street and I overheard these crazy guys talking about how the writers left clues hinting that Optimus Prime was Jewish. I started laughing when I heard it, and after seeing this it's kinda weird to hear it again.
